Staff Profile

I am a Lecturer (~Assistant Professor) in Computer Science based within the Secure and Resilient Systems group. Prior to this, I was a Senior Research Fellow at the Smart Card Centre (SCC) within the Information Security Group (ISG) at Royal Holloway, University of London. Here, I was funded at Royal Holloway through the EU Horizon 2020 EXFILES, unifying European law enforcement agencies, the private sector, and academia to develop novel data extraction and mobile security circumvention techniques. Examples include micro-architectural side-channels and fault injections against TEEs, full-disk encryption, and secure boot sequences on mobile devices.

Before academia, I worked in fintech at Atom Bank, the UK's first mobile bank; and at OneSpan, a NASDAQ-listed cybersecurity vendor, working as a research scientist developing new product offerings and enhancements at their Innovation Centre in Cambridge. I hold a Ph.D. in Information Security from the Information Security Group at Royal Holloway, University of London, and a B.Sc. in Computer Science from Newcastle University.

I am always interested in hearing from potential collaborators in the areas of:

• Mobile and embedded systems security.
• Trusted execution environments.
• Side-channel and fault injection attacks.
• New OS primitives and CPU designs for isolated execution.

Please reach out through my university email address.

For student supervisions, if these topics interest you, and you have a solid knowledge of C, assembly, applied cryptography, and operating systems, then please also get in touch with me.

My expertise lies in mobile and embedded systems security, particularly on issues at the interface of hardware and software. This includes trusted execution environments and hardware-assisted methods for enforcing secure execution; side-channel and fault injection attacks; boot-time security; and smart cards, secure elements (e.g. SIM cards) and their applications. I'm also an active member of the Linux and RISC-V communities.

CSC8208: Research Methods and Group Project in Security and Resilience

I also supervise projects in system security from the M.Sc. Computer Science (Conversion Course), M.Sc. Advanced Computer Science, and M.Sc. Cyber Security programmes.
